Over the weekend, Shkreli’s attorneys sought “guidance” from U.S. District Judge Kiyo Matsumoto on the subpoena to testify in front of the House Committee on Oversight and Government Reform, which was first scheduled for Tuesday but was postponed until February 4 due to a major snowstorm. The attorneys noted that they had told Congress that leaving the Eastern and Southern districts of New York violates the terms of Shkreli’s $5 million bail, but the committee responded by saying that it would pursue criminal contempt charges if he did not attend. They asked that if the judge did not grant Shrekli permission to leave the area, that he quash or delay the subpoena so he would avoid those charges.

But Judge Matsumoto granted that permission Monday, modifying his bail conditions in order for him to do so. The order states that Shkreli is allowed to go to Washington on February 4, but he must submit a copy of his itinerary, including travel tickets and accommodations, to the court in advance of his trip, and notify the court when he’s back in New York.

Shkreli has made it clear he would invoke his Fifth Amendment right against self-incrimination and refuse to answer lawmakers’ questions or turn over documents. While any testimony about drug pricing would have nothing to do with the federal case Shkreli is fighting, his attorneys told the committee that his testimony could get in the way of an investigation of another drug company he ran, Turing Pharmaceuticals, which the Federal Trade Commission is looking at for possible antitrust violations.

“Counsel for Mr. Shkreli informed the committee staff by telephone that Mr. Shkreli would assert his Fifth Amendment right against self-incrimination,” his lawyers wrote in their letter to the judge. “We later reiterated that position to the Committee . . . noting that requiring Mr. Shkreli’s attendance in person under these circumstances would only serve to subject Mr. Shkreli to embarrassment and obloquy without serving any of the legitimate tasks of Congress.”

The 32-year-old has been airing his anger over the subpoena and highlighting his Fifth Amendment rights on Twitter since last week, throwing insults at congressmen and assuring them that he will stay mum if he does go to Washington.
